Objectives : Matter: Properties/Identify/Small The learner will be able to identify that matter has predictable properties and is composed of particles to small too be seen with the naked eye. States of Matter: Conditions/Identify The learner will be able to identify states of matter.

STATES OF MATTER The Four States of Matter Four States Solid Liquid Gas Plasma

Gas Has no fixed shape Has no fixed volume Made of particles that move rapidly The particles also have large spaces between them in comparison to solids and liquids

Examples of Gases are Steam Oxygen Carbon dioxide Smog Tear Gas Helium

Liquid Has no fixed shape Has a fixed volume Particles move past one another easily Particles are fairly close, but not in a neat even arrangement as the particles in a solid are

Examples of Liquids are Orange Juice Water Soft drinks Milk Rubbing Alcohol Vinegar

Solid Has a fixed shape Has a fixed volume Particles are arranged in a tight, regular pattern Particles move very little

Examples of Solids are Ice Frog Cheese Bricks Wood Popcicle

But what happens if you raise the temperature to super-high levels… between 1000°C and 1,000,000,000°C ? Will everything just be a gas?

STATES OF MATTER PLASMA  A plasma is an ionized gas.  A plasma is a very good conductor of electricity and is affected by magnetic fields.  Plasmas, like gases have an indefinite shape and an indefinite volume. Plasma is the common state of matter

STATES OF MATTER SOLID LIQUID GAS PLASMA Tightly packed, in a regular pattern Vibrate, but do not move from place to place Close together with no regular arrangement. Vibrate, move about, and slide past each other Well separated with no regular arrangement. Vibrate and move freely at high speeds Has no definite volume or shape and is composed of electrical charged particles

Some places where plasmas are found… 1. Flames

2. Lightning

3. Aurora (Northern Lights)

The Sun is an example of a star in its plasma state

Writing Activity The students will describe the three states of matter and include the following : At least one example of each state A description of each state
